I bought a forerunner 955 watch 3 months ago. Although the battery is full, the watch does not turn on when I turn it off or when it turns off while updating. After leaving it on charge for a long time, it turns on after pressing the power button for about 1 minute for a very long time. For example, yesterday while automatically installing the 20.23 beta update, the watch turned off and wouldn't turn on for 1 day. Today I was able to turn it on by trying different key combinations. Where do you think the problem is?
